    • Sealing devices such as packers comprise a shape-memory material having a compressed run-in position or shape and an original expanded position or shape. The shape-memory material may comprise a polyurethane foam material held in the compressed run-in position by an adhesion material that is dissolvable by a fluid. The fluid may be a wellbore fluid already present in the wellbore or a fluid pumped down the wellbore after the sealing device is disposed within the wellbore. The fluid may also be a production fluid from the well. Upon being contacted by the fluid, the adhesion material dissolves and the shape-memory material expands to its original expanded position or shape, thereby sealing and dividing the annulus of the wellbore.
    • 诸如封隔器的密封装置包括具有压缩的入口位置或形状和原始扩展位置或形状的形状记忆材料。 形状记忆材料可以包括通过可被流体溶解的粘合材料保持在压缩的输入位置的聚氨酯泡沫材料。 在密封装置设置在井眼内之前,流体可以是已经存在于井眼中的井眼流体​​或者在井眼下方泵送的流体。 流体也可以是来自井的生产流体。 当被流体接触时,粘合材料溶解并且形状记忆材料膨胀到其原始的扩张位置或形状,从而密封和分割井眼的环。
